To all whom it may concern:

Be it known that we, FRANZ XAVER BOD- NAR and SAMUEL LEIB KREPPEL,citizens of Austria-Hungary, and residents of Vienna, Austria-Hungary,have invented certain new and useful Coin-Operated Lock Mechanism, ofwhich the following is a specification.

Patents have been granted for this invention in Austria, No. 47 1,809,dated May 20, 1897; in Germany, No. 92,906, dated April 21, 1897; inFrance, No. 258,540, dated November 18, 1896;. in, England, No. 17,453,dated August 22, l896, and'in Switzerland, definitive, No. 13,253, datedSeptember 28, 1896. 1

Our invention is a coin-controlled portfolio adapted for the receptionof papers and documents, and it is capable of variation as to form tosuit different requirements as to shape and size necessitated by thedifferent kinds of papers or documents to be contained.

Our invention is particularly adapted for use in connection withnewspapers or periodicals which may be inclosed therein from inspectionand use until the required coin is introduced into the device to releasethe looking mechanism.

1n the drawings, Figure l is a perspective View of the portfolio orbinder. Fig. 2 is a view of the portfolio open. Fig. 3 is a view of thelock with part of the casing removed. Fig. 4 is a sectional view on line3 3 of Fig. 3. Figs. 5 and 6 show details of the lockingbolt andcatch-hook. Fig; 7 is a detail view of a paper-clamp.

The portfolio or temporary binder consists of two leaves or sides 1 2,hinged together at top and bottom. The hinges comprise the sections 3,secured to the sides, and the connecting-pieces 4, hinged to the saidsections by hinge-joints, thus forming a double hinge connection whichwill keep the sides at the back a fixed distance. apart and will insurethe alinement of the'locking devices hereinafter described. Theconnectingpieces 4 support the. clips which hold the rod by which thepapers or documents are held.

The locking mechanism is placed between the leaves or sides at or neartheir free edges,

and this mechanism comprises a catch 6 on one leaf projecting at rightangles to the face of the leaf and adapted to pass through an opening 7in the side 8 of the lock-casing 9, which casing is fixed by screws orotherwise in an opening in the opposite leaf. A'locking-bolt 10 engageswith its end the notch 11 of this catch, and thus locks the leavestogether. The bolt is carried by an arm 12,'pivoted to a plate'13, whichis screwed to the frame-bars 14 of the faceplate 15 of the lock-casing,so that the arm movesjbetween this face-plate 15 and the plate 13. Aspring 16, also between the plates, presses the arm constantly in adirection to normally engage the locking-catch. The bolt is bent up'fromthe lever-arm, so. as to overlie the reduced part 13' of the plate 13and to pass through the up rightguide 13" thereon. The lever-arm has -astud or projection 17 on one side adjacent to the edge of thecam-slide'18, which is located between the plates 15and Band is guidedby a pin 19 thereon, working in a slot 20 of the plate 13, and by. thehandle or knob 21, passing from. the slide throughi'a slot in theface-plate of the lock-casing. The coinslide has an opening 22 toreceive the coin of proper size from the coin-slot23 in the faceplatev15, and the slide is pressed normally up by a spring 24, carried on theinner side ofthe plate 13 and'engaging the slide, so that its opening isnormally in position to receive the coin from the coin-slot. A spring issecured to the face of the plate 13, and the end of this is bent to liein the line of movement of the coin. The opening in the coin-slideextends to the edge of the slide, and the coin when in the openingprojects slightly therefrom, and when the slide is moved the edge of thecoin bears directlyonthe projection 17 of the bolt-lever 12.] Thisaction forces the lever-arm backward and retracts the bolt sufficientlyto unlock the portfolio. The 1e yer-arm 12 has a pin 12 thereon,.andthis is engaged by a retaining-lever 25,.which has a forked end 25' toengage the pin when the lever-arm 12 is retracted. The retaining-leveris set in position to engage the pin 12 immediately after the lever armis retracted, and for this purpose the retaining-lever is ofrightangular form and is pivoted at its elbow to the face of the plate13, its arm 25" having a cam edge which extends across the slot 20before mentioned and into the path of the pin 19 on the coin-slide,being normally pressed into this position by the leaf-sprin g 26,bearing on the arm 25", and having its other end secured to the plate 13by the pin 27.

In the movement of the coin-slide with the coin in place the lever-armof the bolt is first retracted through the direct action of the coin,and then the pin 19 strikes the cam edge of the right angular retaininglever and moves said retaining-lever against the pressure of its spring,so that its hook 25' will be directly in front of the pin 12 just atthis time, and while the retaining-lever is so held the coin in thecontinuous movement of the slide releases the projection of thelever-arm and allows the leverarm to have avery slight movement underthe action of its spring, so that the pin 12 will firmly engage the hookof the pivoted retaining-lever. The operating-knob of the coin-slide nowbeing released by the operator, said slide will return at once to itsformer position, while the locking-bolt will remain retracted by thepivoted catchlever. The bolt is not retracted far enough by the coin toget entirely out of alinement with the catch-hook 6 on the other leaf orside of the portfolio; but it is simply retracted far enough to destroythe locking action of bolt. The bolt and catch may still have contactwith each other; but this contact is a sliding one and is intendedmerely to give in the final separation of the catch-hook from thelocking-bolt a slight retracting movement to the latter sufficient torelease the pin 12' from the pivoted retaining-lever and allow thelocking-bolt to be set free to engage the catch-hook when the portfoliois closed.

It will be seen from Figs. 5 and 6 that the catch-hook has a fiatsurface 28 for engaging the locking-bolt to secure the full lockingeffect and a rounded orinclined bearing-surface 29 to engage theinclined end of the locking-bolt.

When the parts are locked, the bolt engages the fiat part of thecatch-hook, and when the bolt is retracted by the coin its inclined endis brought into alinement with the incline on the catch-hook, and in thefinal opening movement of the catch-hook or separation of the same fromthe locking-bolt this incline, acting against the inclined edge of thelocking-bolt, will retract the latter sufficiently to release the boltfrom the retaining-lever 25, and immediately the catch-hook leaves thebolt the latter resets itself for another locking action, as do also allthe other parts.

prevent the withdrawal of the coin when once it has been used to operatethe device.

I The casing 13 has an opening 13 through which the coin may fall intothe bottom of the casing, from where it may be removed through the door31 when the same is unlocked by operating the lock 32, carried on thedoor.

The casing-plates and operating parts may be stamped up into shape.

In order to hang up the portfolio, each leaf or side has attached to itsupper edge a hook 33, facing in opposite directions, so that when theleaves are closed these hooks, overlapping each other, will form asuspending-ring.

It will be noticed that in our invention the weight of the coin plays nopart at all, but that the parts are operated entirely by direct contactof the coin transmitting the force applied by the operator to thecam-slide.

Our invention is not limited in its applica tion to portfolios, but maybe used on drawers and in like situations, and the mechanism may be usedin any positionvertical, horizontal, or, in fact, upside down.

If the cam-slide is operated without the presence of a coin therein, thelocking-bolt will not be retracted. The retainer will be operated; butthis will have no effect, as the pin 12 will simply be received in thenotch V of the retaining-lever, and the retaininglever will again assumenormal position as soon as the coin-slide is released. This action ofthe retaining-lever with its notch V will for the time being effectuallylock the bolt against retraction, and thus the device cannot besuccessfully tampered with.

The newspapers may be held in place on the rod before mentioned by atubular clamp X.

A plate y is used to cover the retaining-lever, its spring, and thebolt.

What we claim is 1. A coin-operated lock mechanism comprising a swingingbolt, a lock-hook adapted to be engaged thereby, a movable coin-carrierhaving a recess to receive the c0in,a projection on the bolt adapted tobe engaged by the coin and be moved thereby to unlock the bolt, andmeans for holding the swinging bolt in its retracted position,substantially as described.
